To all whom 'it may concern.'

lle it known that I, Janse S. WnN'rwon'rH, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain Improvements in Assembling-Machines, of which the following descri tion, in connection wlththe accompanying rawings, is a specliicatlon, like reference characters on the drawings indicating like parts in the several figures.l

A'lhis invention relates to machines for use in the manufacture of boots and shoes and is herein shown as embodied in a mavhine for use in assembling the parts of boots and shoes and for tittin such parts to the last preliminary to the pu ling-over and lasting operations.

In the assembling operation as heretofore practised. it has been usual for the operator to place the counter, box toe, upper and lming loosely about the last, arrange these parts in their correct relative positions, and then drive a tack through the middle part of' the rear of the heel to temporarily secure the assembled elements of the shoe together.

These operations have either been performed by hand, or with the aid of a machine. In some instances it has been proposed to drive two anchoring tacks through the assembled shoe materials, one at the hack of the heel, and the other through marginal portions of the counter and upper which had been wiped over upon the innersole at the center of the rear of the shoe. The use of a single tack at the back of the heel or of two tacks which were located substantially at the extreme rear end rtion of the shoe to secure the assemble arts of a shoe together I believe to be insu cient for this purpose. Under some other practices of assembling the upper was stretched longitudinally of the last with a view to fitting it to t e lines of the last at the sides and also in order to draw the upper and counter snugly against the heel end portion of the last. While there were substantial advantages gained over prior practices by this method some of the benefits due to straining the upper lengthwise of the last were lost for the reason that .no provision was made to anchor the up er at the sides of the counter following t e longitudinal Stretching. It is well known that the free ends or wings of the heel stiiener have a tendency to swing down between the upper and the side of the last during the operations preparatory to lasting and that the lasting machine operator usually is obliged to pull up these stilfener ends as an earl Step in lasting the rear part of the shoe. Il is highly desirable that some means be provided in the machine which rforms the assembling operation for securlng the stillener ends against such displacement and thereby saving the time of the lasting machine operator. It is also desirable that means be provided to obtain a snug Ht of all of the upper materials to the side faces of the last at the front ends of the heel stili'- ener at or in the neighborhood of the heel breast line, and that said upper materials be secured at these points in such manner as to maintain close relation to the last until the completion of the lasting operation.

In order to overcome many of the objections heretofore found to exist in assembling machines, and furthermore to secure the result above referred to, a very important feature of this invention consists 1n a novel construction and arrangement of means for seizing an upper at the forepart and stretching it in a direction lengthwise of the last, so as to strain the upper about the heel end and to cause it to closely conform to the lines of the last at the sides of the counter. and means for anchoring *he upper to the last at the heel portion of the shoe in such manner as to maintain the stretched upper in close relation to the last at those points where it is desirable that it should be snugly fitted. In the construction shown the upper at the forepart is preliminarily strained ina lateral, as well asa longitudinal direction relatively to the last, to the end that it may be brought snugl up to all of the curves of the last at the fore part and stretched approximately into the position that it will finally assume in the finished shoe. To this end` in the herein illustrated embodiment of the invention, I employed three grippers` one of which is located at the toe end, and the others are located one on each side and at substantially the ball of the last. These grippers are supported for movements, and are actuated, in outwardly divergent paths, the toe end grip er moving in a direction which is incline( upwardly and forlio ' ing member above the wardly relatively to the toe end of the shoe and the side grippers moving upwardly and laterally away from the op osite sides of the shoe bottom. To secure t e best results in iitting the upper to the sides of the last the illustrated machine embodies means for pressing the upper and counter of the shoe against the last at the sides, and at the rear end of the hee and for wiping the marginal portions of the upper and counter over upon theinnersole and securin them in position, while the upper is under engthwise strain, vsuch means for sha ing the upper at and adjacent to the edge o the shoe bottom constituting a further eature of the invention the utility of which is obviously not limited to machines of the particular ty e illustrated. The pressing means may a vantacgeously be in the form of tyeldingly mounte (pads which are located low and closely a jacent to the wipers so as to coo rate therewith in forming a well-dened e ge on the u per and counter about the heel end of t e shoe. ,For securing the upper and the counter in position the mac ine shown, has means for driving fastenin s through the wiped-over portions at the si es and at the end of the heel, the side fastenings being located substantiall at the front ends of the side portions o the counter.

In the illustrated machine the last about which the parts of the shoe to be assembled are loosely arranged is supported on a pivoted jack and the grippers are sup `oi-ted upon a pivoted frame and said jac and frame are automatically carried, as an entirety, rearwardly while the u per is under the described lengthwise and ateral strain, and at the'same time the pressing, wiping, and fastening mechanisms are moved forwardly to meet the shoe, and the upper and counter are pressed against the sides and rear of the heel. The shoe is then clamped,

and the machine comes to rest in order to permit inspection of the shoe. When the machine is restarted the fastenings are driven, and the several parts are then returned to their former positions. The performance of these several operations, automatically and in sequence, insures uniformity in the a pearance of the finished shoes, and saves la I regard the mechanisms for accomplisliin these results as important features of this invention.

Another important feature of the invention lies in the means for clam ing, and unclampin the shoe. In the il nstrated machine this is comprised in two down-holds, which are adjusta ly supported trom a slidthe last when the jack is moved to t e rear, and operating means, including a common actuating lever, which is yieldingly connectr on the part of the operator. i

sition occu ied by ed with both the jack and the down-holds. When the last is to be clamped, the actuating lever is moved b its cam in a direction to force the downolds and jack yieldingly against the last, and upon a reverse movement of said lever the down-holds and ack are separated for unclamping the last. n connection with such mechanism, a maiiually-operable lever and connections are provided or permitting the operator to unclamp the Jack and return it to the front of the machine in order that the shoe materials may be inspected and, if needs be, further ad]ustments of the upper about the last effected. Other features of the invention, including important details of construction and conibmations ofparts, will be hereinafter more speciicall referred to and claimed.

g 8 in the. loose In the preferred embodiment of the invention the starting and stoplping of the wer shaft 4 is effected throng a one-revo ution clutch, and as the geared connections between this shaft and the cam shaft 7 are in the ratio of 2 to l the machine is brought to a stop when the shaft 7 has completed a semi-rotation, and is ril-started by a second depression of the controlling treadle to complete the cycle of operation.

An suitable form of one-revolution clutch may employed to secure this result. As shown in Figs. 8, 9 and 10, the loose pulley 5 is provided with a series of holes 8 arranged circumferentially about the shaft 4. The shaft 4 has keyed thereto a frame 0 within which slides a spring-pressed pin 107 which is arranged to enter in one of the holes pulley to clutch the latter to the shaft. An arm 108 is pivotally connected at one end to the frame 9 and is provided with a square recess which receives a nut l10, said nut being affixed to the clutch pin 107, and being mounted for pivotal movement in the recess of the yoke by screws provided with set nuts, as shown in Fig. 9. The outer free end of the arm 108 is deflected laterally as shown in Fig. 8, and is also beveled to coperate with the beveled end 111 is pivoted at 113 of a bell crank wedging member 112 which to a rigid part of the frame of the machine. The arm 114 of the wedging member carries a pawl 115 which is normally held by a spiral spring so that its f ree end rests against the ledge 116 projecting rigidly from the arm 114 of the wedge member. The controlling treadle 117 is fulcrumed to the frame of the machine, and a rod 118 extends from its inner end to a bell crank 120 which is pivoted to the frame of the machine.4 The upper end of the bell crank 120 is slotted to receive a pin 122 projecting laterally from a slide 124 which is guided for movements in suitable ways on the frame of the machine. A spring 126 forms a connection` between the upper arm of the bell crank 120 and the frame of the machine and normally acts to maintain the bell crank and slide to the rear, and the controllingr treadle 117 in elevated position, as shown in Figs. 1 and 9. The pin 122 extends through the slide 124 and over the pawl 115 so that when the treadle is depressed and the slide moved toward the front of the machine the pin will act to depress lthe arm 114 of the wedging member 112 and thereby move its end 111 away from the free end of the arm 108 and permit the pin -107 to enter one of the holes 8. A spiral spring 128 connects the arm 114 of the wedging member with a bracket or other fixed part of the machine frame and acts with a normal tendency to rock the wedge member so as to locate its beveled end 111 in the path of movement of the free end of the arm 108. A rubber buffer 130 is located below the beveled portion at the upper free end 111 of the wedgi ng meme ber and when the machine is brought to a stop the coperating beyeled surfaces of the member 111 and arm 108 are in engagement and the end of the arm rests on the rubber buffer. In this position of said parts the locking pin 107 is withdrawn from clutching engagement with a hole 8 in the loose pulley 5, and hence said pulley turns freely on the power shaft 4. When the treadle 117 is depressed, however, the pin 122 on the slide 124 is moved against the upper inclined surface of the pawl, thereby turning the wedging member 112, disengaging its upper free end from the arm 108, and permitting the spring-pressed pin 107 to enter one of the holes 8 to clutch the loose pulley to the power shaft 4. When the pin 122 has traveled over the pawl 115 the spring 128 will return the wedging member toits normal position with its end 111 in the path of the free end of the arm 108, so that when the shaft 4 completes a rotation the arm 108 will reiingage the wedging member, the locking pin will be withdrawn from the hole which itloccupied in the loose pulley, and the main shaft 4 will be brought to rest. When the treadle 117 is released by the operator the spring 126 will cfl'ect a rearward movement of the slide carrying the-pin 122 which latter will return to its starting position. the pawl 115 being lifted by the pin duringI such movcment. A sto pin 132. which is rigidly connected to the iiiame of the machine. lies in the path of movement ot' the ledge 116 and by its engagement therewith limits the upward movement of arm 114 of the wedge member when saidmember is returned to position for unclutching` the pulley from the shaft by the spring 128. Features of this starting and stopping mechanism are claimed in a divisional application Serial No. 257,727, filed on October 11. 1918.

The last upon which the parts of the shoe are to be assembled is preferably supported upon a jack 48 which carries at its upper end a pin to enter the usual jack pin socket of the last. The jack is shown as being pivotally sustained at 21 upon a bar 47 which is mounted to slide in suitable guideways which may be conveniently carried by a portion of the main framel of the machine. as shownyin Fig. 1. The lower portion of the bar 47 is provided with a plurality of holes. whereby it may be pivotally connected. with capacity for adjustment. with the end of the )ack-operating lever 46. The lever 46 is fulcrumed by a pin 46'L to a block which slides on a guide rod 46n projecting rigidly from a horizontal member of the machine frame. The fulcrum block is located between two spiral springs 49, one of which is confined between said block and said frame member, and the other between the be inore block and a uut which is secured to the outer end of the rod 46, the lutter of these springs being stronger than the former. 'l he rear end portion ol' thc lever 46 is shown as being curved upwardly and at the extremity thereof it carries u cani roll 45 which rests upon a cani 145, designed as shown in Fig. 3 ot' the drawlugs. An extended portion of the lever 46, beyond the roll 45, has connection with one end of a strong spiral spring 450, the opposite end of this spring being connected to a rigid portion of the frame, and the spring acting to hold the roll in yielding engagement with the cam. In Fig. 3, the roll is shown as resting on the highest portion of the cam in which position the lever 46 has its forward end lowered, thereby holding the jack 48 depressed. A continued rotation of the cam 145 in the direction indicated by the arrow will permit the roll 45 to pass from the high to the low point of the cam, thereby permitting the spring 450 to move the 'ack from its lower position as shown in l"igs. 1 and 3, to its upper position, as will fully explained hereinafter.

At a suitable int above its connection with the bar 47 t e jack 48 is provided with a plurality of holes.. to one of which is pivotally connected a link 22, the opposite end of which link is pivotallv connected to one arm of a bell crank 24. e pivotal connection between the link 22 and the bell crank 24 is capable of adjustment as the bell crank is provided with a plurality of holes which are respectively located different distances from the fulcrum of the lever. The lower arm of the bell crank 24 carries a roll 26 which has engagement with a cam 28 fasten the cam shaft 7 and an extension from the arm of the bell crank 24 is connected with the upper end of a strong spring 260 whose lower end is secured to the frame of the machine, said spring acting to hold the roll 26 in yielding engagement with the cam 28. This cam is so designed that, at the proper time in the cycle of operation. of the machine, the r'oll 26 by passing down to the low art of the cam will, through the bell cranll 24 and links 22, swing t e jack 48 rearwardly so as to carry the last and upper materials thereon from the position shown in Fig. 1 of the drawings, to a rearward position, for a purpose to be hereinafter explained.

The 'ack 48 has a rigid forward extension 1 which is provided with an opening or guideway to receive a bar 10 for supporting the three rippers which are preferably employed in t is machine, one gripper bein located at the extreme1 end of the toe,an one on either side of the shoe, at a oint approximately o posite the ball. T e upper end portion o the bar 10 is provided with a block 10l which rests upon the extension 134 of the jack. Knuckles 13G having pins which turn freely in sockets in the block 10* are provided, one at the front ot' the block, and one on each side thereof, as shown in Fig. 1. Rods 138 are pivotally connected at their lower ends with the knuckles 136, the upper ends of these rods carrying lates 140 to which rods 142 are pivoted, said) rods being adjustable through clamping bolts 144, which pass through se mental slots at the upper portions of the p ates 140. Suitable (gripper carriers 146 are adjustably secure to the rods 142 by set screws 148. The gripper carriers sustain grippers 150 which latter may be of any desirable construction, but as herein shown comprise members which are independently pivoted to their carrier and have engaging 'aws, and handles, with springs interposed tween the handles and acting to yieldingly force the jaws together. These grippers are opened by hand to disengage the upper materials of a shoe, and are closed automatically by their springs to engage the upper materials when the handles are released.

The supporting devices for the grippers are constructed and arranged in such manner as to hold the three grippers in divergent relation to the shoe supported on the jack 48 in order that the u per when engaged by the grippers may lie held in outspread relation to the last. As shown in Fig. 1. the supporting rod 138 for the toe end grippers is inclined forwardly relatively to the bar 10. and also to a line perpendicular to the plane of the shoe bottom when a shoe is on the jack, and is connected by a rod 152 with an arm 154 which is pivoted to the jack 48. A spiral spring 156 is confined between a collar on the rod 152 end of the arm 154. bears against the rod 138 for supporting the toe gripper. this means the toe gripper support is yield ingly maintained in a forwardly inclined relation to the frame of the machine. The

adjacent the forward and a washer which side grippers supports are similarly maintained in an outwardly divergent relation to the vertical median line of the machine by suitable struts 160 which, as shown in Figs. 1 and 2, extend from the side grippers supporting rods A188 to the supporting rod for the toe end gripper, and are yieldingly connected to the latter by s rings 162 which are confined between bloc s carried by the toe gripper rod 138 and nuts on the ends of the struts 160.

The bar 10 is pivotally connected with a rod 162 havingthereon a spiral spring 164 which is confined between a collar 162 rigidly secured to the rod and a collar 162" which slides on the rod, and is provided with a pin which enters a slot at the outer end of a lever 12, fulcrumed at 165 to a bracket depending from the frame of the lthe pin when the jack is machine. The rear end of the lever 12 is provided with a plurality of holes to form an adjustable, pivotal connection with the link 14, whose opposite end is pivotally connected, with-similar capacity for adjustment. with the end of a lever 16 which is fulcrumed to the frame of the machinesand at its rear end carries a roll 18 which engages a cam 2() fixed to the cam shaft 7. An extension of the lever 16 is connected with one end of a strong sprin 266 whose o posite end is fastened to tie frame of t e machine, said spring acting to hold the cam roll 18 in yieldin engagement with the edge of the cam 20. his cam is so desi ned that, at theA proper time in the c cle o the machines operation it will, t rough the described connections including the spring 164, yieldingly raise the bar 10 and the several grippers and, by reason of the forwardly inclined relation of the toe gripper rod 138 and the laterally inclined relation of' the side gripper rods 138 to the path of movement of bar 10, ex'ert an upward and outward pull upon the upper materials which have been seized by the grippers, to hold such materials in an outspreud condition. The forward component of the pulling force which is applied to the toe end gripper through the described construction serves to strain the upper longitudinally of the last, and to maintain it in close relation to the sides of the last so that it fits snug] the curves of the last.

Referring again to the jack-controlled mechanism, a shaft 166 is suitably mounted in bearings in the main frame of the machine, and rigid therewith is a handled lever 104 which projects toward the front of the machine and in convenient position for manipulation hy the operator. An arm 168, also rigid with the shaft 166, projects toward the front of the machine, and at a suitable angle to the handled lever 104. The arm 168 overlies an extension of the pin 2l which pivotally connects the jack 48 with the bar 47 and may, by a suitable movement of the lever 104, be made to engage in an elevated position. Another arm 170 projects rigidl from the shaft 166 undy is located in position to engage the rear portion of the jack 48, upon depression of the lever 104. By this construction the operator is enabled to effect a manual depression of the jack when it is raised, and additionally may move the jack from its rearward position,`to which 1t was moved through the cam 28 and connections as above described, to a forward position. when desired. During such manual depression of the jack the lower spring 49, and the spring 450, or either of these springs, will yield suitably to permit such movement. lt will also be seen that as the gripper-s carrying frame is connected with Vis clamped to the down-hold 105 b the jack by the extension 134, the gripers will follow the movements of the jack w en the latter is carried from its position as shown in 1, to its rearward osition, and vice versa. On the other han as the bar 10 slides vertically in the aperture through the extension 134 the grippers carrylng frame is capable of movement vertically independently of the jack to permit the grippers to be raised for exerting a pull on the upper to draw the upper materials against the heel end of the last, and along the sides of the last, so that the upper will he snugly fitted to the lines of the last and the tendency to spring away from the sides of the shoe will be prevented.

Referring to Figs. 1 and 3, the rear portion of the frame of the machineis provided with a standard 172 havin therein a vertical `groove 174, and a slide :1 carries a rib fitting the groove to thereby guide the slide vertically. The slide 71 is attached to the lever 46 by a rod 176 provided near its lower end with a fixed collar 178, the lever 46 being connected by a pivot 50 with a sliding block 177 which is normally forced against the collar by a spring 180, the latter being confined between the block and a retaining nut 181 which is threaded to the lower end of the rod 1,76. The upper portion of the slide 71 is provided with a transverse aperture which receives a bar 182, and a suitable clamping screw 183 secures the bar to the slide with capacity for adjust ment in the aperture in a direction transverse to the slide. Secured to the forward end of the bar 182 is a down-hold 105, which is arranged to engage the rear portion of the last bottom for, clamping the last to the jack when the slide 71 is depressed. The upper portion of the downhold 105 is provided with a transverse aperture to recelve, adjustabl a rod 184 which a set orward end of t e rod screw 105. The f 184 is provided with a vertical aperture to receive, adjustably, a second down-hold 30, a suitable set screw 30* being threaded in an aperture at the forward end of the rod 184 to adjustablv clamp the down-hold 30 in position. hen the jack with a shoe thereon has been moved to its rear position, as indicated by dotted lines in ig. 3, the down-hold 30 will be directly over the fore part of the last, while the down-hold 105 will be directly over the heel ortion of the last, and by the described a Justments the down-holds may be arranged at the appropriate relative heights, an at such dlstance apart in a direction longitudlnally of the last. to engage with the last bottom at sultable points to eEect a rigid clamping of the last and the shoe thereon against the jack .when the jack and down-holds are moved toward each other. It will be seen that when the cam roll 45 passes from the high point of the cam 145 to the low int thereon the upward movement of the nt end of the lever 46 will raise the jack, while the downward movement of the rear portion of the lever will simultaneousl depress the down-holds and thus firmly c amp the shoe in position to receive the fast which will be. thereafter driven throu the upper materials at the heel yend of t e shoe to secure such materials in finally assembled condition on the last. The described movements of the 'ack and downholds will be effected ie dingly through the sprin 49, 180 and 50.

Exten ing rearwardl from the freine of the machine is a rigi ,bracket 186 which through a pin sustains a link 187 having at its upper end an angular extension in which is a segmental slot, and a clamping screw 189 passes through the slot and is threaded into the bracket. The lower end of the link 187 is pivotally connected to the back gage 190 which extends toward the front of the machine and is there provided with a laterally curved portion shaped toreceive the rear face of t e heel portion of a shoe. A link 191, arranged substantiall parallel with the link 187, and also pivotally connected to the bracket and back gage, but at points in advance of the link 187 coperates with the latter in effecting a parallel-movement connection'between the back gage and its supporting bracket. Upon loosening the clam screw 189 the back ge may be adjust/e to proper position or receivin the rear part of the shoe when the latter as been moved with the jack to its rearward position, and preliminary to the insertion lof the astenings.

In the illustrated embodiment of the invention the upper, lining, and counter are wiped over upon the bottom of the heel portion of the shoe at three separatev points,-

namely, at the center of the rear of theheel, and on each side of the shoe at points substantially in line with the breast of -the heel. YIn order to effect the desired inward wiping, and the securem'ent of the overwiped shoe materials at these points, the machine. is provided with three wi ers, and with associated staple-forming an driving mechanisms. A pad is co eratively associated with each wi r an andarranged to yie dingly press the upper materials against the edge of the last as the wiper -is advanced to wipe the u standing materials over and down u on t e shoe bottom. One of the sta le orming and driving mechanisms an its associated wiser and pad lare shown in Figs. 4 to 7, an the arrangement of the several wipin and fastening mechanisms relativel to eac other is best shown in Figs. 1 and The machine. frameis provided with two is constructed laterally extending brackets 192, and a rearwardly extending bracket 193, to which are connected links 42, the latter being in turn pivoted at their u per ends to the rear end portions of suite le raceways 41", havin thereon racewa covers 41 which are a justabl secure to the raceways by screws 410 w ich are threaded into the raceways and pass through inclined slots in the race- Wag7 covers. In this way the covers are caa le of being clamped at different distances rom the tops of t e raceways in order to accommodate suitable staple strips of varying de rees of thickness. The forward portions o the raceways 41l are provided with molding surfaces comprising a pluralit of oppositely beveled portions 41, 41, w ose angular relation to each other progressively increases toward the end of the raceway, and

extending from the forward one of thesey several molding surfaces is an anvil 194 having the formation of a flat strip of metal and which extends part way into the driving aperture 196 formed in the staple driving tube which terminates in a nozzle to be located over the ed of the shoe. A driver 198, ri id with a iver rod 198", and having a attened portion 198.is supported for reciprocating movements in the aperture 196, and a spiral spring `19,9 is confined between a n ut at the lower end ofsaid driver tube and a sliding collar200, which is 1ocated near the upper end of the tube and is secured b a pin 200 to the-driver rod. The upwar movement of the sliding collar 200 is limited by a stopcollar 201 which is adjustably-secured to the driver rod dguiding tube. The upper extremity of the river rod is provided' with a head 202, as shown. Secured to the sliding collar 200 is a staple former, comprising three members, two of which, 41l and 41, are sha ed to correspond, respectively, with the mo ding surfaces 41 an 41", and the third one, 41 is shaped to fit over the anvil 194. The construction and arran ent of thestaple former members and t e staple molding surfaces and anvil are such that they will act, successively, to

bend the stallalle portions of a Hat staple strip S, such as sown in Fig. 7, as the same is fed toward the driver, into U-shaped staples of the form shown in Fig. 6. A staple strip Yfeeder, comprising a bifurcated pawl 203,

which is pivotally supported on the lower end "of a lever 204 pivoted in tiirnto a bracket on the raceway, isoperatively controlled by the movement of the staple former, the relation of the parts being such that when the driver rod is forced downwardly the pawlwill be carried to the rear` and moveover the strip of`sta les, but as the driver rod rises a forwar movement will be imparted to the pawl to advance the strip toward the driver a distance equal 'to the width of one staple. A. retaining pawl 205 is yieldingly forced against the strip of staples and acts to prevent retrograde mo tion thereof during the backward movements of the feeding pawl 203. Assuming a completely formed staple to have been fed. through the advance of the staple strip. into the position shown in Fig. 6 where it projects beyond the forward eml of the anvil 194. and into the aperture 196, and the succeeding portions of the staple strip being in various degrees of formation, as shown in Fig. 4, when the driver is actuated downwardly its forward edge will sever the leading staple fromv the strip and drive it through the driver aperture 196 and into the upper materials which have been wiped over upon the bottom of the shoe. The same movement of the driver will cause the staple formers 41, 41 and 4l' to coiiperate with the anvil and molding surfaces at the end of the raceway in the formation of other staples, which latter will he successively formed. cut ofi'. and driven into the work upon the succeeding downward movements of the driver.

Each of the wipers 7() is pivotally connected near its forward end to a lug 206 depending from a raceway. and preferably has a convexly-curved. beveled lower surface so as to turn smoothly the upstanding upper and counter at the heel of the shoe over upon the innersole. Each wiper is located below a staple nozzle and is provided with an aperture to receive the nozzle. The rear end of the wiper bar is perforated to receive a guiding rod 208. which is threaded into the raceway and has au adjustable stop nut 209 for limiting the upward. pivotal movement of thc rear end of the wiper and the consequent extent of normal depression of the front end of the wiper relatively to the plane of the shoe bottom. A spring 214 is confined between the lower surface of the rear end portion of the wiper and a head 211 at the lower end of the rod. The pad 44 for engaging the edge portion of the shoe adjacent cach wiper is carried by the lforward end of a rod 20T which is guided in holes formed in two lugs projecting from the wiper. a spring 20S being confined between the pad and one of said lugs for yieldingly urging the pad toward the shoe. The pads 44 are preferably of rubber` felt. or other soft. or elastic material to prevent marring of the upper. The three staple forming and driving mechanisms together with their associated heel seat wipers and pads are. at the proper time in the cvvcle of the machiues operation.

moved simultaneously toward the. heel end of the shoe. two of said mechanisms heilig caused to engage the shoe at points substantially in line with the breast. and the third at the central portion of the rear of the heel. To secure this operation three levers 40 are provided which are fulcrumed at 400 to the ,will be seen that frame of the machine on pivot pins arranged, respectivsly, to permit two of the levers to move in opposite directions laterally, and the third lever to move longitudinally of the machine, and said levers havel pivotal collections 210 between their forked upper ends and the wipers at points to the rear of the pivots 206. The lower ends of the. levers -10 are pivotcd to blocks 211 that slide vertically on guide rods 38, depending from a .'pider 36, which is mounted for vertical sliding movements in the fraaie of the machine. Spiral springs 37 surround the rods 38 and are coniinedbetween the. spider and the top of each'block provide yielding connections between Vthe spider and the levers 40, and stop collars 40 are secured at the ends of the rods for retaining the blocks 211 thereon. A rod 35 secured to the spider 36 is provided with an adjustable, rigid collar 212 havinga pin which is engaged by the forked end of a lever 33, fulcrumed to the machine frame and having its opposite end connected with the strap 32 of an eccentric 31 which is fast to the cam shaft 7. By this construction, when the cam is rotated in a manner to cause its strap to raise the rear end and depress the forward end of level' 33 the spider will be moved down and through its connections with the levers 40, which include springs 37, will yieldingly actuate these levers so as Vto move their upper end portions and the wip. ers and stapling mechanisms carried thereby from the positions shown in Figs. 1-2 to the positions where the wipers will engage and wipe in the upper materials about the heel end of a jacked shoe. Subsequently. upon further rotation of the cam the spider will be raised until, through engagement of collars 40 with the blocks 211, the levers 40 will return the wipers and staple mechanisms to their positions as shown in Figs, 1 and 2. Following the described inward movements of the wipers and Staplers the drivers will be actuated to drive staples and secure the, overwiped the. counter and upperimto the innersole,`1t being understood that thewipers and pads will be retained until the fasteners are completely driven. This result is Acured by the sliding connections between the blocks 211 and spider 36, the springs 37. and the eccentric 31. as the lost motion between the spider and blocks is sutiicient to permit the staples to be com* pletely driven into the shoe beforethe eccentric has elevated the spider far enough for the collars 40 to engage the blocks and effect reverse movements` of the levers 40. It

the upper arms of. the levers 40 and the links 42 constitute, with the raceways and the supporting base for the levers and links, parallelograms which insures that the stapling mechanisms will be 211, and.

material .-ineludin in engagement with the shoe counter ilat down upon t advanced into driving positions in planes substantially parallel with the shoe bottom. In view of the fact, however, that the wipers and pads have connections with stapler-s by pivots 206, and with the levers 40, by pivots 210, they may rock to adapt their positions to the contour of the last, the springs 214 yielding to permit such movements. In ractice the nuts 209 are preferably so ad usted that the forward ends of the wipers rst enga. e the upper at points slightly below the ge of the last bottom and are caused to ride up and over the edge of the last b the pressure of engagement between t e last and the beveled and curved surfaces of the wipers, the adjustability of the nuts, however, permitting the normal relation of the wipers to the plane ofthe shoe bottom to be varied to cause them to encounter more or less resistance in their operative movement, as may be required by the character of the shoe materials. During the upward movement of the forward ends of the wi s they assume inclined positions and their rear ends are depressed thereb compressing the springs 214, and when t eir wiping portions clear the edge of the last the s rings 214 cause the wipers to act yielding y on the upper, the`wi rs being then advanced over the edge o the last to wipe the upper and e innersole. During this operation the ads 44 engage yieldingly the sides and'en of the last and press the upper tightly against the immediately l adjacent points where the wipers are acting.

The wipers and pads thus coperate in forming a sharp angular edge of the u per and counter .about the heel portion o the last. While in the embodiment of the in vention as herein illustrated and described I show only three wipers and pads with their associated sta le-driving devices, it is to be understood t at if desired a greater number Vof these instrumentalities may be employed, and that the wipers and pads may be sufleientlv close to each other to completely last the heel seat of a shoe.

The several sta le driver rods are simultaneously actuate by a hammer y106 which is provided with a rectangular guiding aperture to fit over and slide vertically upon the down-hold 105, the latter being formed of rectangular cross-section. The hammer is connected by a link 112 with a driver arm 74, which is pivoted to the bracket 186 and is driven by a strong?.` spring 75. The driver arm has a slot' as indicated by dotted lines in Fig. 1 within which is journaled a .roll 216. A slide 81, which has a projection to enter a vertical groove 217 formed in the` standard 172, whereby it is guided for vertical movements, carries at its upper end a bifurcated rojection 82 carrying two rolls 82 located below the arrn 74. The forks of this pro-l jection are located, respectively, on each side of an L-sha )ed tri: pau'l 72 pivoted to a bracket rigi Vwith t e frame. The pawl has a vertical arm which is arranged to be located at times, under the roll 216 to hold the driver arm and hammer in raised position, a s ring 218 acting upon a horizontal arm of t lo pawl and forcing its end against a hooked projection 220, (sce dotted lines Fig. 1) formed in a part of the' frame of the machine, to maintain the pawl in such position. An arm 120 is connected with the projection S2 of the slide 81 and extends through the slot in arm 74 to a point above the arm where it carries a roll 120 which overlies the horizontal arm of the trip pawl. A rod connects the slide 81 adjustably with the slotted portion 76 of a lever 76, which lever is fulcrumed at one end to a bracket rigid with the frame and carries at its opposite end a cam roll 78. The cam roll rests upon a cam 79 which is fast to the shaft 7, and is provided with a dropped portion D. A strong spring 222 is connected at one end with the lever 76 and at its opposite end to the machine frame and holds the cam roll in yielding engagement with the cam. When the several drivers have been positioned over the edge of the heel portion of an assembled shoe the driver rod eads 202 will be beneath the hammer 106, and the hammer and its actuating mechanism will occupy the positions shown in Fig. 3, with the hammer bar sustained upon the end of pawl 72, the driving spring 75 being then under tension and the cam roll 78 resting upon the high part ofthe cam 79.

Upon rotation of the cam the roll will finally reach the dro ped portion D thereof and the lever 76 an parts connected therewith will be pulled down by the spring 222, causin the roll120 to engage and trip the pawl 2 and thus permitting the hammer to descend under the. influence of its spring and actuate the staple foriners and drivers. U n a continued rotation of the cam, the rol 78 will pass gradually from the lowest to a high point thereon, lifting the slide 81 and causing the rolls 82* to engage and lift the hammer arm 74 against the stress of its spring until the roll 216 passes above the upper end of pawl 72, when the pawl will be moved Vbeneath the roll bv its spring, and will retain the hammer in elevated position, as shown in Fig. 3.

Features of the mechanism herein4 disclosed for forming and driving fasteners are claimed in va divisional application Serial No. 257 ,728, led on October 11. 1918. In the use of a machine, an upper, lining and heel stiener are first placed loosely over a last to which has been applied an innersole, and the last is located on the jack pinof the jack 48 when the several parts of the machine occupy the positions in which they appear in Fig. 1, the jack being depressed, and with the grippers, being tilted forward so that the upper materials are resented conveniently for the operator to e ect the necessary adplstments thereof to the lilies of the last. The upper materials are then carefully arranged about the last in the positions which they are to occupy in the finished shoe, and the grippers 150 are opened by hand, and then permitted b their closing springs to grip the u per at t e end of the toe and at the two si es of the shoe, as shown in Fig. 1. The operator then ste s on the starting treadle 117, withdrawing t e wedge 111 from engagement with the arm 108, thus permitting the loose pulley to be clutched to the .driving shaft and starting the machine. Thereafter, through the cam 20, roll 18, lever 12 and s ring 164, the grippers frame will be raise causing the grippers to exert through the spring 164 a yielding pull upon the up r which will be pulled upwardly and slig tly outwardly at the forepart of the last, the longitudinal strain effected by the toe end gripper causing the up r to be drawn snugly about the heel ende and close in along the sides of the heel. The direction of the pull which will be exerted by the grippers is such that the upper materials will e fitted to the sides of the last in a manner to prevent the formation of any wrinkles or bagginess, and particularly alon the shank. Following the described pulling of the upper to the lines of the last the jack carrying the last and upper materials, together with the grppers and their sup orts, will be moved, as an entirety, and w ile the upper is held by the grppers, from their positions as shown in Fig. 1, toward the rear of the machine until the heel end of the shoe meets the curved portion of the back-rest 190, thelast being then located beneath the two down-holds. Simultaneously withV the rearward movement of the shoe the wipers 70, pads 44,

- and their associated staple forming and driv.-

ing devices are movedinwardly toward the shoe, the wipers engaging the upstanding up er and counter at the rear end of the heel an at the two sides opposite the breast line and bending these materials over and wipin them down upon the innersole, and the pa s pressing the materials firmly against the side and end portions of the last. The roll 45 thereafter passes from 'the high to the low part of the cam 145 and, throu h the described connections, raises the jac with tlie shoe thereon and the ip ers-carrying frame. and simultaneous v dit resses the down-holds 30 and 105. The s oe is thus pressed firmly against the wipers to effectually flatten -the overwiped material down upon the heel seat portionof the innersole, and is also Vsecurely clamped between the jack and down-holds in position to receive the fastenings. At this point the driving shaft 4 will have made one complete rotation and the end of the clutch-actuating arm 108 will engage the beveled portion 111 of the wedging member 112, thereby uncluthing the shaft from the loose pulley and bringing the machine to a stop. Opportunity will then be afforded the operator to inspect the shoe so as to determine if the u per materials are properly positioned on t e ast, and to make an required adjustments of the upper to the ines of the last before the fastenings are driven. If it is desired at this stage to temporarily relieve the shoe from the clamping engagement between the jack and down-hold, the operator will pull down on the handle 104, thereb depressing the jack and tilting it forwar toward the front of the machine, the springs 49, 450 and 260 yielding as the rolls 45 and 26 are lifted ofi' of their cams. The upper and other shoe materials may then be adjusted, and upon the release of the handle, the jack will auto-1 matic-ally return the shoe to its clamped position. Having satisfied himself that the parts of the shoe are properly assembled, the o erator then depresses the treadle a second time and starts the machine. The cam 79 having previously elevated the slide 81 and, through the rolls 82, raised the hammer arm 74 and placed the driver spring under tension, and the arm having been retained in such position by the pawl 2, as shown in Fig. 1, upon further rotation of the cam the pawl will be tripped, and the staple drivers actuated to drive staples through the overwiped upperof the shoe. Thereafter the several parts of the machine will be returned to their original positions, as shown in Fig. l, and the machine brought to a stop with the jack presenting the assembled shoe to the front of the machine in order that the operator may remove the shoe and insert in the machine another last with the upper materials thereon, and the above-described cycle of operations will be repeated.
